How does blockchain check the historical transaction of an accou

Transaction mode of bitcoin

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

The relevant certificates can be issued online for the data of blockchain storage and network forensics through easysaving. Through the record number on the certificate, the blockchain query can be concted directly through the official website of easysaving and relevant arbitration commission, including the preservation subject, preservation time stamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information

Through the record number on the forensics certificate, you can also directly query the blockchain on the official websites of easy security, notary office and Arbitration Commission, including the preservation subject, preservation timestamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information, so as to ensure the openness, transparency and traceability of blockchain storage data

2) if it is "blockchain technology", the network also has a good interpretation, and all walks of life are also trying to combine with blockchain technology in new fields. Maybe in the future, blockchain technology will be used correctly instead of being used to deceive people
3) if it is "blockchain information", you can go to all kinds of blockchain media or financial media, and almost every day there are relevant blockchain instry information and news reports. Such as: Babbitt, coin you finance, blocknet, golden, daily, etc
4) if it's "blockchain audio", you can go to Himalaya FM, litchi micro class, qianchat and other platforms. For example, the audio related to "voice of money", "Yu Lingxiong", "Wang Feng" and some other financial media blockchain is also good, with various dry goods and in-depth analysis
therefore, the above four points are all related to blockchain. It depends on your choice.
